South Americans set records

The opening day of the knockout stage featured four South American teams vying for a spot in the quarterfinals. The first game went the distance, with host Brazil beating Chile 3-2 in a penalty shootout.

Brazil reaches its sixth straight World Cup quarterfinals with the result, while Chile is once again eliminated by Brazil for the fourth time in four World Cup knockout round appearances.

The hosts will face Colombia, which reached its first World Cup quarterfinal with a 2-0 defeat of Uruguay, in Fortaleza on Tuesday (4 ET on ESPN).

Here are five notes on the opening day of the knockout stage:

Brazil, making its sixth consecutive appearance in the quarterfinals, owns the second-longest active streak of any team, behind only Germany's 15. The Selecao becomes the first team to eliminate another country from four different World Cups with the win over Chile and extends its World Cup shootout record to 3-1, winning each of the past three.

Host nations have now won four straight World Cup shootouts and are 4-2 overall.

David Luiz turns home his first goal for Brazil.

David Luiz struck first in the game, giving Brazil the early lead in the 18th minute. Although it was a controversial goal, as it appeared to glance off a Chilean player, the goal goes into the record books as being Luiz's first ever for his country in his 40th international appearance.

Brazil, which entered the game with an 82 percent chance of winning -- according to ESPN's Soccer Power Index -- did not look its strongest. The host nation completed just 71 percent of its passes against Chile, its third-lowest figure in a World Cup game over the past 50 years.

However, the result means that Brazil does remain undefeated in 61 straight competitive (non-friendly) home games, last losing in 1975.

Alexis Sanchez's game-tying goal in the 32nd minute ended up being the strike that sent Chile to its first extra-time game in a World Cup. With the goal, Sanchez became the first Chilean with two goals in a World Cup since Marcelo Salas in 1998.

However, Brazil's goalkeeper, Julio Cesar, saved the day for the hosts when the game finished still tied after 120 minutes of play. Cesar stopped two of Chile's five shots in the ensuing penalty shootout, ensuring that his team lives to play another game.

James Rodriguez rifles an absolute stunner past Fernando Muslera.

Colombia was led by two goals from its prolific young striker, James Rodriguez.

He has scored in each of Colombia's games at this tournament, becoming the first player to score in each of his team's first four games at a World Cup since Brazil's Ronaldo and Rivaldo both did in 2002. Rodriguez's two goals Saturday give him a tournament-leading total of five and he has now scored in six straight games for his nation.

Juan Cuadrado has also been a key player for Colombia, leading all players at this World Cup with four assists, including on Rodriguez's second goal Saturday.

Colombia has won all four of its games at this tournament after having won a total of three games over its previous four World Cup appearances combined (13 games).

Colombia is winless in 12 straight games against Brazil after last beating its continental rival in 1991. The game will be only the second matchup of CONMEBOL teams in the World Cup quarterfinals (Brazil-Peru in 1970).

It's the latest that two South American teams have met in any World Cup since the 1970 semifinals (Brazil-Uruguay) and the sixth meeting in the quarterfinals or later.
